To all whom 1125 may concern: 1

Be it known that I, ERASTUS E. WVINKLEY, a citizen of the United States,residing at Lynn, in the county of Essex and State of lvlassachusetts,have invented certain new and useful Improvements in Automatically-Controlled Shoe-hlachines; and I do hereby declare the following to be afull, clear, and exact description of the invention, snchwas will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to automatic machines in which the requisiterelative movements between the work and means for operating thereon areautomatically controlled and efl cctcd to maintain the workand-operating means in proper relation as the point of operationprogresses along the work In welt and turn sewing machines, outsolestitchers, rounding and channeling machines, and various other shoemachines, it is necessary during the feed of the shoe to change theangular relation of the operating means and work by relatively tippingthe operating means and shoe both transversely and longitudinally of theline of feed to maintain the operating means and shoe in the properrelation at the point of operation. It is the primary object of theinvention to provide novel and improved mechanism for accuratelydetermining and effecting the relative transverse and longitudinaltipping movements requisite for'maintaining the operating means and workin the proper posi' tions. To this end the invention contemplatescontrolling the corrective tipping movements by thecontour of the workalong or adjacent to the path of travel of the point of operation alongthe work. The longitudinal and transverse. tipping move. ments arepreferably thus controlled by feelers arranged to act along the shoeadjacent to the path of. operation of the operating means, and connectedto determine and control the corrective movements imparted to theshoe'or operating means by the tipping mechanisms. The preferred form ofthe invention is especially designed for use in an automatic machine forsewing the inseams of welt or turn shoes, and in the drawings theinvention is shown embodied in such a. machine.

In addition to the features outlined above,

the invention includes further features of form; Fig. 2 is a sideelevation showing the mechanism for swinging the jack; Fig. 3 is anenlarged detailed view showing the sewing mechanism and feelers, andparts of the mechanism controlled by the feelers; Fig. 4; is a frontelevation of the parts of the controllingmechanism shown in Fig. 3; Fig.5 is an elevation of parts of the controlling mechanism similar to Fig.3, with certain parts removed to more clearly show the parts behind;Fig. 6 is a sectional view on line 6, Fig. 3; Fig. 7 is sectional viewon line 7, Fig. 3; Fig. 8 is a sectional view on line 8, Fig. 7 Fig. 9is a side elevation of the mechanism for tipping the sewing head, .andshowing on a larger scale the side of the mechanism opposite to thatshown in Fig. 1; Fig. 10 is a plan view of the mechanism shown in Fig.9; Fig.1l is an end view of the mechanism shown in F ig, 9, lookingtoward the left. in said figure, and toward the right in Fig. 1; F igs,12 and 13 are end and plan views showing in detail parts of themechanism for controlling the tipping of the sewing head; Fig. 14 is aplan view of one of the roll carriages forming a part of the mechanismfor tipping the sewing head; Fig. 15 is a sectional view, partly inelevation, on line 15, Fig. 14; Fig. 16 is a sectional elevation on line16, Figfl l; Figpl7 is a sectional plan view indicating parts of themechansm for stopping the machine at thecompletion of a shoe; F 18 is. asectional elevation on'line 18, Fig. 17;; and Figs. 19 and 20 aresectional details on line 20, Fig. 17, showing the clutch controllingvalve in different positions.

In the drawings the invention is shown as embodiedin a machine similarin some respects to the machines shown and described in Patents Nos.1,082,185, December 23, 1913, and 1,088,890, February 24-, 1914. In thismachine the means for operating on the shoe consists of a sewingmechanism which 5 is similar in construction to the wellknown Goodyearwelt and turn sewing machine shown and described in Patent No. 412,704,October 8, 1889. The shoe to be operated on is carried on a freelymovable and rotatable jack which is automatically swung during thesewing to maintain the bottom of the channel or base of the insole lipinthe line of feed by correcting mechanism which is controlled by a feeleracting along the channel approximately at the sewing point. The sewingmechanism is mounted on a support or head which is automatically tippedboth transversely and longitudinally of the feed during the sewing tomaintain the sew ing mechanism in proper relation to the surface of thesole at the sewing point by correcting mechanisms which are controlledby feelers acting along the surface of the sole adjacent to the channeland approximately at the sewing point. For the sake of simplicity it ispreferred to utilize the same feeler for controlling the swingingmovements of the jack and the longitudinal tipping movements of thesewing mechanism, the horizontal position of the end of the feelerdetermining the swing of the jack, and the vertical position of the endof the feeler determining the tipping of the sewing mechanisn'i. Thetransverse tipping of the sewing mechanism is determined and controlledby the vertical position of a second feeler, which engages the shoe solewithin the channel.

In the machine shown, the shoe supporting jack and mechanism forswinging it is substantially the same as that shown and de scribed inPatent No. 1,088,390. The jack 2 is secured upon the upper end of asleeve 4 which surrounds a shaft 6 mounted in the outer end of asupporting arm 8. The ack is forced yieldingly toward the sewingmechanism by a spring engaging one arm of a bell crank lever 10, theother arm of which engages a collar on the sleeve 4. The sleeve is freeto slide vertically upon the shaft, and is connected to turn with theshaft by means of a yoke 12 secured to the upper end of the shaft,having one of its arms slotted to embrace one of the arms of the jack:The rear end of the supporting arm 8 is mounted to turn freely about ashaft 14 which is mounted in bearings in the outer end of a second arm16, the rear end of which is mounted to turn freely upon a shaft 18mounted in the frame of the machine. These supporting devices permit thejack to be moved freely in any direction for presenting a shoe to thesewing mechanism, and in manipulating it during the feed of the shoe.The shoe is swung while the The mechanism. for swinging the jack andshoe comprises a two-way Horton clutch 24 which is connected with theshaft 6 through sprocket chains indicated at 26, and fully shown anddescribed in the patent above referred to (Figs. 1 and 2). The clutch isengaged and disengaged at proper intervals through a lever 28 operatedby a cam carried by a cam shaft 30 which is continuously driven, andmakes one revolution for each cycle of the sewing mechanism. The drivingmember of the clutch 24 is operated through a lever 32 connected by alink 34 with a sliding bar 86, and operated by an actuating lever 38through a link 40, one end of which is connected with the bar 36, andthe other end of which is connected to a block mounted to slide in asegmental slot formed in the lever. The slot in the actuating lever isarranged to extend on opposite sides of the fulcrum of the lever, andthe extent and direction of movement imparted to the clutch, and throughit to the jack, will depend upon the position of the block with relationto the fulcrum of the lever. The block is shifted in the actuating leverthrough a lever 42, one arm of which is connected by a link 44 to thelink 40, and the other ann of which is connected by a link 46 to thelower end of a controller cam plate 48 which is pivoted to one arm of abell crank lever 50, the other arm of which carries a roll engaging acam on the cam shaft 30. The upper end of the controller plate 48 isprovided with a V- shaped mouth, the sides of which form opp'ositelyinclined cam surfaces for engaging a controller roll 52 carried by onearm of a bell crank lever 54, the other arm of which engages a cam onthe cam shaft 30. At the time the controller cam plate 48is raised byits actuating cam, the bell crank lever 54 carrying the controller roll52 is free of its cam, and the position of the roll is determined by afeeler engaging the channel of the shoe, the roll being in central orneutral position in case the point engaged bythe feeler is in the lineof feed, but being displaced either one side or the other of its neutralposition in case the point engaged by the feeler is ont of the line offeed; If the controller roll is out of neutral position when thecontroller cam )late is raised, one of the inclined cam suraces on theplate viii-ride against theyroll, swinging'the plate, and through thelink 46 and arm412 moving the pivot blockin theactuator lever 38 out ofline with thefulcrum ofthelever, and

The free end ofthe .feeler finger 74 is forced yieldingly 1 againstthesurface of the shoe sole by a springSO, and is1forced, horizon-.tally against -the base of the channel by 35f spring 82 acting on thearinofthe bell crank carrying lever76. The horizonjtal arm of the bellcrank lever is connectedby a. link- 84:

The cam releases the roll carrying leverand allows the feeler to rengage the base of the channel after thechannel guide and awl have advanced to feed the shoe.

The sewing mechanism is mounted upon a support 100, and comprises achannel guide 102, a welt guide or-back gage 10 1, a feeding awl 106, aneedle 108, and the usual cooperating stitch forming devices. Thechannel guide and feed awl may, if it is found desirable, be mounted tomove vertically on the-feed slide to accommodate themselves to theVertical position of the surface of the sole, and may be brought intoproper vertical relation to the needle previous to the passage of theneedle through the stock by levers 110 and 112, asindicated in Figs. 1and 3,

and more fully explained in Patent No.

1,030,043, June 18, 1912.

The support or head 100 for the sewing mechanism is mounted to slide onse 'n'lental ways 1141 which are concentric with the point of operationof the sewing mechanism, so that by moving the head upon the ways thesewing mechanism may be tipped transversely of the line of feed aboutthe point of operation of the sewing. mechanism. The ways 11 1 areformed on the end of rotary carrier 116. mounted to turn about ahorizontal aXis passing through the point of ,operation' of the sewingmechanism, so that by turning the carrier the sewing mechanism may betipped longitudinally of the feed about the point of operation of thesewing mechanism. The mechanism for moving the head 100 on the ways 11%comprises a re ciprocating roll-carriage 118 connected by a link 120 toa lever 122, which in turn is connected by a link 124 with the lower endof a. lever 126, they upper end of which bearsagainst a sleeve 128mounted to slide on the carrierllG, and connected with the headthrough-a bar 130, lever 132, and links 134;

and 136, as more fully described in Patent drum 1 12. The rolls aremounted in roll car- I riers 1% which are pivotally supported in thecarriage. The outer ends of'the roll carriers are provided with arms146, the ends of which are connected by a link 14-8, so that the rollcarriers Wlll move 111 unison." so

long as the rolls arefin position with their axes parallel totheaxis ofthe drum, they will rotate idly in contact with the drum, and nomovement will be in'ipartcd to the roll carriage. If, however, the rollsare turned at an angle, then they will travel lengthwise of the drumuntil their axes are again parallel to the axis of the drum, thus movingthe roll carriage on its ways in one direction or the other, accordingto the direction in which the roll carriers are turned. Movement of theroll carriage in either direction will, through the connectionsclescribed, tip the sewing mechanism transversely, and the transversetip of the sewin mechanism will be determined by the position of theroll carriage along the drum, The position of the roll carriage isvaried and determined through a controller inthe form. of a roll 150carried by a sliding bar 152 and arranged to be engaged by a controllercam 154. The controller cam is in the form of a sleeve mounted to rotatewith and slide longitudinally on a shaft 156, which makes one revolutionfor each cycle of the" sewing mechanism. The cam is provided with acentral groove 158 having a width approximately the diameter of thecontroller roll 150, and is also provided with oppositely inclined camsurfaces 160 leading to the groove 158. The cam sleeve is also providedwith an annular groove 162 arranged to en; gage a roll on the short armof a lever 16%, the long arm of which is connected by a link 166 withthe link 148' connecting the arms of the roll carriers.

If the controller roll 150 is in line with the central groove 158 of thecontroller cam at the time the roll enters the groove, the roll passesidly through the groove and the roll carriage, and consequently the headsupporting the sewing mechanism remains in position. If the controllerroll is at one side or the other of this position, however, when itenters the groove 158 in the controller cam, one of the cam surfaces 160will ride against a roll, shifting the controller cam sleeve on itsshaft and swinging the lever 164;. This movement of the lever will turnthe roll carrierarms 146 and turn the rolls at an angle to the drum, sothat the rolls will travel longitudinally of the drum until, by reasonof their travel, they are brought into position with their axes parallelto the axis of the drum. The movement thus imparted to the roll carriagewill change the lateral tip of the sewing mechanism.

The position of the controller roll 150, and consequently the lateraltip of the sewing mechanism, is determined by a feeler finger 168 whichis pivoted to the arm 78 and pressed against the surface of the sole bya spring 170. The free end of the feeler finger is arranged to bear uponthe sole just within the channel, and approximately in transversealinement with the sewing point. The feeler finger is in the form of alever, the outer end of which. is connected by a link 172 with thehorizontal arm of a bell crank lever 174, the vertical arm of whichcarries a controller roll 176. Cooperating with the controller roll is areciprocating controller canr plate 17 8 provided with oppositel'yinclined earn surfaces 180. The controller cam plate is formed on thefront end of an arm, the rear end of which is pivoted to lever 182mounted on a stud 184 and carrying near its upper end a roll 186'whi'chengages a groove 188 formed in an arm projecting radially from a disk190 (Figs. 3, 4, 5 and (3). The controller cam plate is moved toward andfrom the controller roll by a lever 192,- the forward end oil which isconnected to the cam plate by a link-194, and the rear end-of wh'ichcarries a roll engaginga 196 secured to a shaft 198. which makes onerevolution for each cycle of the sewing mechanism. The disk 190 isconnected with the bar 152 which carries the controller roll 150 bywires 200 and 202 which pass over suitable guide rolls and have theirends secured tothe bar and disk. The controller roll 176 is locked inposition during the" movement of the controller cam plate toward theroll by a We'dging roll clamp which is a duplicate of the clamp shown inFigs. 3, 7 and 8' for locking the control-lcr roll through which thelongitudinal tip of the sewing mechanism is controlled. T is clampcomprises a drum 204 secured to the outer end of the shaft which carriesthe coi'itroller' roll carrier lever 174, and cooperating wed-ging rolls206 arran ed between the surface of the drum an eccentric surfaces onthe wedge blocks 208. The rolls are forced into wedg-ing or lockingposition by springs 210,; and are forced out of locking position by thehorizontal arins 212 of connected bell cranklevers 214. The upperbellcr'a'nk lever is provided with an upwardly projecting arm 216" whichis connec'ted to one arm of lever 218, the other arm of which isconnected loya link 220 with the forward end of a lever 222,-the rearend of which carries a roll engaging a cam secured to the cam shaft 198.A clamping lever 22 i is forced" against the" periphery of the disk 190'bye can 226, exce t during the reciprocation of the controll'er'camplate 178.

The feele'r' finger 168' by its engagement with the" surface of the shoesole positions the controller roll 176, and at aboutthe time in thecycle 01": the sewing mechanism that the feed of the shoe has beencompleted, the roll is locked in positiom-and the controller cam plate178 is moved downward toward the roll. If the roll is not in position toenter the slot between the cam surfaces 180, one of the cam surfaceswill ride against the roll,-moving the controller cam plate and rockingthe lever 1-82 andthe connected disk 190; This movement of the disk 190will shift the bar 1 52, carrying the controller T011 150 into apositioncorresponding to the position of the end of the feelerl The bar 152 willthen be locked, and the controller cam plate 178 willbe immediatelyraised to free it from the controller roll 176 and the controller rollwill be unlocked; While the needle is through the work the controllercam 154 will act upon the controller roll 150 to vary the lateral tip ofthe sewing mechanism, in case the feeler has indicated a change in thelateral inclination of the shoe sole between the point engaged by thefeeler during'this cycle and the pointengaged by the feeler during thepreceding cycle. Should the lateral inclination of the sole at the pointengaged .by the feeler be. the same as the lateral inclination at thetpoi'nt engaged thereby during the preceding cycle, the controller roll17 6 will be brought to the same position by the feeler during eachcycle, and there will therefore beno change in the positionof thecontroller roll 1'50, and consequently no change in the positionof theroll carriage and lateral inclination of the sewing mechanism. WVheneverthere is a change in the lateral inclination of the sole, however, therewill be a corresponding change in the position to which the .controllerroll 176 is brought, ELDClLEL corresponding change in the position ofthe controller roll 150, which will cause a change in the position ofthe roll carriage, and in the lateral inclination of the sewingmechanism. When the bar 152 carrying the .controller roll 150 ispositioned by the feeler and eonnected controlling mechanism, it islocked in position during the action of the controller cam 154 thereonby a clamp 228 yieldingly mounted in a clamp lever 280 which is operatedby. a cam 232011 the shai't156. The lever is held in engagement with thecam by a spring pressed pin 284 mounted in the leve'r and engaging oneof theguide plates which retains the bar in its (Figs. 12and 13).

It will be seen that through the mechanism above .described thefeelerduring each cycle of the sewing mechanism detects any change inthe lateral inclination ofthe sole, and sets the correcting mechanism sothat this mechanism will, during the time that theneedle is in the work,effect a correspondingchange in the transverse inclination of the sewingmechanism, thus maintaining the shoe'and sewing mechanism in properrelation transversely of the .feed during the transfer of the point ofoperation of the sewing mechanism about theshoe.

The mechanism for turning the carrier 116 to tip the sewing mechanismlongitudinally of the feed is similar to the mechanism for tippingthesewing mechanism transversely, and comprises a roll carriage 236 mountedto reciprocate, on guide rods 238, and connected with the carrier 116through guideway a link 2,40, bell crank lever 242, and link 244 QFig-s;l, l0 and 1.1).? Therolleairiage carries two rolls engaging the drum 142mounted in roll carriers provided with eon nected arms 246 through whichthe roll carriers may be turned to cause a travel of the carriageineither direction along the drum. The position of the roll carriagedetermines the longitudinal tip of the sewing mechanism, and theposition of the carriage is controlled and determined by. a controllerroll 248 anda cooperating controller cam sleeve 25-0 mounted on a shaft252 and connected with the roll carrier arms 246 through a lever 254 andlink 256. The controller roll 248 is carried on a sliding roll carrierbar 258, and the position of the roll and bar is controlled anddetermined by a shoe engag ing feeler and .connecting mechanism which isa substantial duplicate of the mechanism for controlling and determiningthe position of the controller roll 150, the position the sewingmechanism. The roll carrying bar is clamped in position during theoperation of the controller cam 250 by a clamp lever 260 correspondingin'eonstruction to the clamp lever 230.

For the sake of simplicity the controller finger 74 which controls theswing of the jack is also utilized as the controller finger forcontrolling the longitudinal tip of the sewing mechanism. In theconstruction shown the outer end of this finger is connected by a link262 to a bell crank lever 26:4, the upper end of which carries acontroller roll 266. A coiiperating controller cam plate 268 isreciproeated by a lever 270 and cam on the cam shaft 198, and actsthrough a lever 272, roll 274, and grooved radial arm 276 on the disk278 to turn the disk in accordance with the position of the controllerroll 266. The disk 278 is connected through wires 280 and 282to thecontroller roll carrying bar 258, so that the movement imparted to thedisk 278 through the controller cam plate 268 determines theposition ofthe controller roll 248. The controller roll 266 is locked in positionduring the operation of the controller cam plate 268by thelocking'mechanism shown in Figs. 7 and 8, and already described.

During each cycle of the sewing mechanism the end of the feeler finger74 engages the surface of the sole at the base of the channel andpositions the controller roll 266, thus determining through thecontrolling mechanism described the position, of the roll carriagelongitudinally of the drum, and consequently the longitudinal tip of thesewing meehanism. So long as the longitudinal inclination of the shoesole at the point of operation is unchanged, the controller roll 266will bebrought to the same position by the engagement of the feeler withthe shoe during each cycle, and there will be no change in the positionat the roll carriage l of which determines the transverse tip of and inthe longitudinal tip of the sewing mechanism. When any change in thelongitudinal inclination of the sole at the point of operation occurs,this change will be detected by the feeler, and will result in a changein the position of the controller roll 266, and a consequent change inthe position of the controller roll 248. This will cause the rollcarriage to travel longitudinally of the drum in a direction and througha distance corresponding to the setting of the controller roll, thuschanging the longitudinal tip of the sewing mechanism to correspond tothe change in the longitudinal inclination of the shoe sole.- Thus theshoe and sewing mechanism are automatically maintained in properrelation longitudinally of the feed during the transfer of the point ofoperation of the sewing mechanism around the shoe.

In the machine shown, the various mechanisms of the machine are driventhrough a main driving shaft 284 through a clutch 286 which is engagedby the operator after placing the shoe upon the jack and bringing itinto engagement with the sewing mechanism at the point where the sewingis to begin, and which is disengaged automatically when the sewing hasprogressed to the desired point on the shoe. As indicated in Figs. 1 and17 to 20, the clutch is engaged and disengaged through toggle levers 288connected at one end to a fixed pivot 290, and at the other end to abell crank lever 292 which engages the movable clutch member. Theknuckle of the toggle is connectedto a rod 294, the rear end of whichcarries a piston 296 fitting within a cylinder 298. The cylinder isconnected by a pipe 300 with a valve casing 302. A valve 304 is mountedin the valve casing, and is carried on the end of a rock shaft 306. Theforward end of the rock shaft carries a treadle 308 through which theoperator may rock the shaft to bring the valve into thepositionindicated in Fig. 19, thus connecting the pipe 300 with a pressuresupply pipe 310. When the valve is moved into this position, the airpressure admitted into the cylinder 298 will operate the piston 296 tostraighten the toggle and thus engage the driving clutch. The valveshaft is latched in this position against the tension of a spring 312 bya latch 31%. The valve is retained in this position until the sewing iscompleted by the latch. hen the seam has reached the desired point onthe shoe, a cam 316 secured to a plate 318 on the yoke 12 engages theforward end of a tripping lever 320, the rear end of which is connectedby a link 322 with the latch 314 and trips the latch to release thevalve shaft 306. The valve shaft is immediately rocked by the spring 312into the position indicated in Fig. 20, thus opening the-end of the pipe300 and. relieving the pressure on the piston 296, so that the spring324 may disengage the clutch, thus stopping the machine.

It will be noted that in the construction described the shoe sole formsin effect a pattern or form along which the feelers travel, and that therelation between the feelers and the form engaged thereby is unaffectedby the action. of the mechanisms which tip the sewing mechanism, since.the feelers are mounted independentlyof the head which supports thesewing mechanism. It will also be noted that the head tipping mechanismswhich are controlled by the feelers are rendered active to move the headand sewing mechanism upon a change and only upon a change in theposition of the corresponding feeler when in controlling contact withthe sole. These peculiarities are inci dental to securing the relativetip between the sewing mechanism and shoe by tipping the sewingmechanism. F eeler controlled mechanisms having these generalcharacteristics may be used with advantage in various machines, and arewithin the purview of the present invention as defined in certain Of theclaims.
